NOTE: Breakout\ Breakin descriptions are as follows:
1. Routing where trace is 3.75 mil wide and 4mil spacing is implemented to escape\ enter BGA
2. The Breakout \ Breakin Length is defined from the pin of the BGA, to where 4 mil spacing
increases to the required spacing per SI recommendations.
a). Data\Ctrl = 12 mil edge-to-edge (e2e) for Stripline
b). Data\Ctrl = 18 mil edge-to-edge (e2e) for Microstrip
